Going stricly by the computer on the X I'm getting 9 mpg! But this is my first tank of gas in it...I just got it. It's a pretty sick love affair though!

 

+1 That's why I'm staying out of this one...

 

If you maintain the v10, only use ford filters, coolant and the motorcraft blend oil... It make take you forever before doing a swap!

 

Typically bigger engines with more torque kept to low RPM and low load are more efficient than smaller engines that run higher speeds.

As an example: my 1970 impala with the 400 small block, turbo 400 transmission, 2.37 rear end, and 2 barrel carb will fetch 15-16 MPG on the highway at 70-75 MPH. That's a big car with a big engine and no overdrive.

 

That old Impala was actually set up better than most with overdrive transmissions! The next big thing in heavy trucks are direct-drive transmissions with super tall gearing; this keeps driveshaft speed down while still putting the engine in the proper RPM range for cruising. Some claim significant efficiency benefits by doing this, I wonder how long it is until this is looked at by light-duty manufacturers.

And, interestingly enough, that little V6 only makes 5 ft-lbs less than the V10 does, and it has an even better torque curve for towing. I used my truck to tow home a minivan for my mother-in-law; total trailer weight was over 9,000 lbs and I never got over 3,000 RPMs the entire trip. It was 52 miles each way with 40 of them being interstate. I hold lower RPMs with this thing than I did with my Excursion!

 

Tom, you know as well as i do the V10 was never meant to hold low RPM's...when you want/need TQ you gotta run it up there, that's how it was designed. the V10 loves to sing along at 5,000 RPM.

btw, i was able to drive our new sales truck set up much like yours...your going to say i'm crazy but i was no impressed. i think maybe i expected to much? idk. it did lug around pretty good though.

 

The EcoBoost is mated with an F-150 for a very simple reason.

It's basically a Taurus with a bed.

The EcoBoost will never end up in a REAL truck. Just because I can tow a sack of potatoes with my daughters Powerwheels Jeep doesn't mean it's a decent tow vehicle.



(Full disclosure: I'm kidding and if the Atlas comes out with a EcoBoost, I'll buy it)

 

I would rather see the new dodge 3.0 diesel swapped in. That would a cool to see or the new cummins coming in the titan.

 

I'd rather just keep driving my 6.0 that weighs 8000lbs and gets 19 mpg Highway and 15 city. ...

 

AMEN!!
